Volkswagen developed the ice-glass


Despite the cold winter, soon many drivers will not have to scrape ice from the windows of their cars. Volkswagen engineers first introduced automotive glass, which does not form frost and ice. They were developed in conjunction with scientists from the Fraunhofer Institute IST in Braunschweig. In contrast to the heated glass, ice-glass due to the physical properties of the coating is not covered by ice – even at -18 ° C. The secret to innovation lies in the fact that the glass is applied to thin transparent layer of indium tin oxide.
“We call this coating Low-E (low thermal radiation). It prevents the heat outside through the interior glass. We are proud of this innovation and boosting its use in all vehicles concern because frost glass is a big plus in terms of comfort for customers, “- said Thomas Drescher of development department Volkswagen.


Electrically conductive coating Low-E glass protects the surface from cooling, not allowing water to condense. The glasses are not covered by a film of ice, because the heat exchange with the outside cold air to a minimum. This is to prevent or slow cooling of the surface of the glasses at low temperatures. However, a significant role is played by certain weather conditions, such as cloudiness, humidity and wind. They have a significant impact on the ice glasses, so, in the words of Thomas Drescher, Low-E coating will not be able to completely prevent the formation of ice and misting, but will significantly reduce the likelihood of their occurrence.

At the current stage of development already has the problem: a new coating prevents the propagation of radio waves, making it difficult to listen to the radio and use a mobile phone in the car. “In this regard, intensive work. Before frost glass appears on the market, it will take some time – says Thomas Drescher. “
